Web Services

Web Services are a standardized way of communication between a client application which consumes e.g. information from a server application in service-oriented architectures. SAP NetWeaver Application Server ABAP can be used both as a provider and a consumer of Web services. You can create, configure, publish, and consume services.

The communication using web services needs to be monitored for errors and performance issues to ensure a smooth information flow.

 

Technical Prerequisites

Performance measurements are based on Real-User Monitoring (RUM) which is also a part of SAP Focused Run. When Web Service performance monitoring is set up, RUM is automatically configured in the background.

Integration Monitoring Setup

Available Monitoring Categories

For Web Service Monitoring, different monitoring categories are available:

  • Web Service (Performance): Can be collected for SAP Java systems or for SAP ABAP systems
  • Web Service Messages (ABAP): Web Service messages collected from SRT_MONI → Message Monitor. Can be collected for ABAP systems. The minimum system requirement to monitor SRT_MONI for Web Services is SAP BASIS 7.02 SP08.
  • ABAP Web Service Consumer: Web service exceptions collected from the SRT_UTIL → Error Log. Can be collected for ABAP systems.
  • ABAP Web Service Provider: Web service exceptions collected from the SRT_UTIL → Error Log. Can be collected for ABAP systems

For the category 'Web Service Messages (ABAP)' you can collect payload information from the web service message and display this payload in the Integration & Exception Monitoring application in SAP Focused Run. You can then use this information to search for related messages in PI or CPI, related IDocs, or related web service calls. Find out how to set up the collection of payload information under Collecting Business Context for Integration & Exception Monitoring.
